Removing actual DPF

I am in the middle of removing my DPF(everything back from the DPF is off) and I notice that the nuts are welded to the flange where the dpf connects to the downpipe. Anybody else have this? Any suggestions to loosen them or get the DPF off? Thanks in advance

Wrench on the bolt, it turns. Nuts are only welded to the flange on the inlet of the emissions garbage

What hawkeye said.. I did the same thing as you and worked on breaking the tac weld and realized that the bolt is not the same as the others and spins freely.

I had that same problem, I used my Impact wrench and broke the first nut off. Do what they said and remove the bolts.

Thanks guys.....think I was looking for a reason to call it quits for the night. Got the bolts off and sensors disconnected. Now trying to figure out how to get the dpf off the rubber mounts and lower it down by myself. Thinking about putting a floor jack underneath it and working it that way. I'll keep you posted.

Get a FlashLight and look at the opposite side of the fastener. There's a regular non-welded nut. I used a air ratchet and a swivel attachment.

For the rubber mounts I used wd40 and had a strap to balance the weight and worked great.also a pry bar of some sort to push out the hangers.

For the hangers, just remove the brackets from the underside of the body, then mess with the rubber and put the ones youll need back on your truck
